Description

technical field [0001] The invention relates to the technical field of thrust measurement, in particular to a force sensor calibration device and a calibration method thereof. Background technique [0002] Engine testing and testing technology is an important part of solid propulsion technology, and thrust vector eccentricity is an important parameter that needs to be measured in engine testing and testing. To study the eccentricity of the engine thrust vector, a large number of repeated experiments are required, and it is impossible to put all these experiments into flight tests. The main reason is that the flight test has high cost, long period, small amount of information harvested, risky, and requires a lot of manpower. This requires the ground test of the engine. The ground test of the engine refers to the static test of the system on the ground according to specific conditions and environmental requirements, and obtains information describing various performance indic...

The main reason is that the flight test is costly, long cycle, small amount of information harvested, risky, and requires a lot of manpower

This requires the ground test of the engine. The ground test of the engine refers to the static test of the system on the ground according to specific conditions and environmental requirements, and obtains information describing various performance indicators of the system, so as to solve the problems in the process of engine thrust eccentricity test. The key issue is that with the development of domestic engine testing technology, some large engines have adopted thrust vector control devices. At present, multi-component force models and multi-component force test benches are mainly used to measure thrust vector at home and abroad, among which the six-point The force measurement method, the six-component force vector thrust measurement technology, needs to connect the moving frame with the fixed frame through the force measuring component, and detect the data related to the vector force through the working force sensor in the force measuring component, but during the measurement process, the working force sensor The accuracy of the working force sensor cannot be determined, especially in the course of multiple tests, the accuracy of the working force sensor is even more uncertain, resulting in a decrease in test accuracy. The prior art uses the method of working force sensor calibration to improve the accuracy of the working force sensor, but the calibration process is complicated , and it needs to be calibrated once without doing a test, which is costly, and some existing calibration technologies also have the problem of complicated process and high cost
